L-胱氨酸辅助溶剂热合成Cu3SbS3纳米结构及表征
摘要: 本文采用生物分子L-胱氨酸辅助溶剂热方法成功地制备了Cu3SbS3半导体纳米材料，并通过X-射线衍射(XRD)、场发射扫描电子显微镜(FESEM)、X-射线能量色散谱(EDS)、X-射线光电子能谱(XPS)和透射电子显微镜(TEM)等方法对合成产物的纳米结构进行了较为详细的表征，研究结果: 以CuCl2、SbCl3 和L-胱氨酸为原料，通过溶剂热法得到了立方晶型的Cu3SbS3纳米棒，棒的直径为100-150nm。研究发现，反应温度为200℃和反应时间为12h 的反应条件能合成得到结晶度最佳，纯度最好的Cu3SbS3 纳米晶。

L-cystine-assisted Solvothermal Synthesis and Characterization of Cu3SbS3 Nanostructure
 
Abstract：In this paper, Cu3SbS3 nanomaterials was successfully prepared via solvothermal method by assistance of the biomolecule L-cystine. The structure and properties of as-prepared product are characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), X-ray energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). Furthermore. Research: The Cu3SbS3 nanorods with the typical diameter about 100-150nm have prepared for the first time by solvothermal method using CuCl2,SbCl3 and L-cystine as raw material. The study found that the reaction temperature is 200oC and reaction time of 12h can be synthesized high crystallinity and purity Cu3SbS3 nanocrystalline.

Key words: L-cystine, Cu3SbS3, solvothermal, nanostructure
